Copyright on state statutes

James Grimmelmann has a discussion over the recent fracas created by the state of Oregon's claim to copyright in its statutes, Copyright, Technology, and Access to the Law: An Opinionated Primer.

In passing, I recently learned that the copy of the ordinances of the Township of Bridgewater (New Jersey) available in the library are NOT the same as the copy available over the internet. One problem that comes to mind is the Sikahema Effect.
